Hi folks,
I've using the TFP method for years with great success, except for times when the water gets too warm (88 degrees) and i miss a couple days without adding chlorine or brushing.
But my problem now is, I cannot seem to get a reading on CCs.
I test the water by adding my R-0870 powder - 10ml turns pink with one scoop.
I add my R-0871 until it's clear - usually 10-14 drops. (CYA at 40 usually)
Then i add the R-0600 reagent to see if i have any CC.
It's always crystal clear. It never turns pink (unless i let it sit for a minute or 2)
I thought i had a defective batch so i bought another bottle.
Same thing.
But i know (i think) i must have CC's, because my pool is getting algae now!
If there is algae growing, then my free chlorine must be attacking it, and thus get partially used up, and be lower than TC, right?
How can my FC and TC both read exactly the same when clearly there is algae eating up my chlorine?
I can't get a reliable overnight reading, since the R-0600 is not showing proper CCs.
In the meantime, I've decided to try a slam this week, basically blindfolded.
It's slamming now, and ive scrubbed everywhere, soaked skimmer parts in chlorine, backwashed, everything out of the pool.
Will likely slam until Friday and hopefully have a crystal clear swim Saturday.
Yesterdays it was a little murky, not bad, but not my usual sparkling clear pool.
Either i'm really missing something, or could i have got bad R600 twice in a row? Exp date is next year.
Has anybody had this issue?
My powder and R0871 are not old either.
I'm open to suggestions folks.
Thanks,
Dan
